BW LPG is set to convert four of its VLGCs to LPG-propelled dual-fuel engines as it prepares for new emissions laws.

The scheme, announced alongside a stronger than expected second quarter report today, will see the retrofitting take place during planned drydockings starting in 2020.

Martin Ackermann, chief executive of BW LPG, says the company has been preparing for IMO 2020 for years.
